Abstract (en)
An integrated core structure (100) suitable for integrating the at least two magnetic components (Lr, Lout, Tr) of a power converter is disclosed, wherein each of the magnetic components (Lr, Lout, Tr) comprises at least one winding (302-1, 302-2-1, 302-2-2, 302-2-3, 302-3).The integrated core structure (100) comprises a plurality of windowed portions (102-1, 102-2, 102-3) and a plurality of perpendicular portions (104-1, 104-2). One of the inventive ideas is that the thickness (116-1, 116-2) of each of the plurality of perpendicular portions (104-1, 104-2) is adjusted to the highest absolute peak value of the resulting magnetic flux that has to flow through the respective perpendicular portion (104-1, 104-2) as a consequence of the aggregation of each of the respective fluxes to be generated by the windings (302-1, 302-2-1, 302-2-2, 302-2-3, 302-3) to be received in the respective windows to be accommodated in the each of the two windowed portions (102-1, 102-2, 102-3) immediately adjacent to the respective perpendicular portion (104-1, 104-2).Thereby, the maximum flux density of the material of the respective perpendicular portion (104-1, 104-2) is not exceeded.
